The Dynamix 1444 Series Monitor Systems accepts the following outputs.
1444-DYN04-01RA Dynamic Measurement Module
Six outputs of two types are provided.
Channel Buffer Outputs
Four outputs, one per channel, are provided via ESD and short circuit
protected +/-20V supplies. The outputs are accessible by BNC connectors or
terminal pins that are independently resistive current limiting protected.
Opto-isolated Outputs
Two opto-isolated open-collector circuits provide TTL signals. The outputs
are suitable for use in providing simple status (on/off )
replicating and transmitting a TTL speed input
01RA module.
1444-TSCX02-02RB Tachometer Signal Conditioner Expansion
Module
Four outputs are provided to allow raw and conditioned buffer outputs.
Raw Buffer Outputs
Two outputs, one per channel, are provided via BNC connectors. These
outputs provide an ESD and short-circuit protected replica of the raw input
signals.
These signals are N/rev. If the BNC output is a multiple event per revolution
signal, the associated status indicator (6 or 7)illuminates blue.
(1) Circuit must include a pull up resistor. See
(2) Using speed signals communicated by an opto-isolated output on one module to a TTL input on another module results in a 180
degree shift in phase measurements on the second module. See
about using the output to replicate speed signals between modules.
